107. Special training in the underground temple (2)

Night in the underground temple.

This place wasn’t a real space but an other-dimensional one, so there was no distinction between day and night, but chronologically, it was already night.

And the Temple of Roia. Erti, who had increased her synchronization with this place, had created a natural night.

But the group didn’t go to bed.

One side of the temple had chambers where people who visited the temple could rest.

When I had entered the underground temple before, this temple was also a mess, just a ruin. But it seemed that Erti had prepared this chamber with her synchronization power.

“Oh my. It seems my synchronization power isn’t that high, so I could only make one bed.”

Lucia replied to Erti’s words.

“I’m fine sleeping on a blanket on the floor, Erti-nim.”

“No. Instead, it’s a wide bed that’s big enough for four people to sleep together. Let’s all sleep together on it.”

So, as Erti said, the group all went up onto the bed. Lucia was very conscious of me coming up onto the bed with her.

“Um… I might smell like sweat… so I’ll go to the edge!”

“Hmm? That’s a reward for a man, you know. There’s no need to be embarrassed. Yulian is a pervert and really enjoys the lewd scent of a female.”

“Is that… really true? Ah, no… still…”

Lucia was flustered by Erti’s lewd talk, so I cut her off.

“I took a bath just now, so it should be fine. You don’t have to worry about smelling.”

As I said that, Undine and Sylph had bathed Lucia and Leister. Of course, I washed up too.

“Heuheu. You seem disappointed. Well, I didn’t even break a sweat dealing with Lucia-ssi today, so I don’t think I need to wash.”

Erti said that, then stuck close to me with a sticky look in her eyes.

“But my skin is full of a woman’s unique milky scent… want to take a whiff? But you can’t get horny. My pussy… no, my body is precious! Unless you praise me a lot before we share sex…”

Ignoring Erti’s nonsense, I just lay down on the bed. It was already night. The others also quietly lay down on the bed and covered themselves with blankets.

A little time passed like that. Not asleep, I thought about the words I had exchanged with Erti earlier.

‘It’s unsettling to leave it to Erti, but Erti said there’s a way to unlock Lucia’s true self, her potential.’

What Erti had told me.

It was an unexpected statement that Lucia, despite being human, had a body like a demon. And Lucia’s future that I had glimpsed through my mother’s future prediction.

She was the most unique case among the heroines with the same S-class destiny rating.

‘She always met a bad ending.’

Actually, even if it wasn’t her. Islend was heading towards destruction, so if I couldn’t stop that future as it was, it would be destruction all the same.

Apart from such external factors, Lucia’s inner self had more complex aspects than the other heroines.

‘It’s like the anxiety of the night.’

The time when people are most likely to feel anxious is naturally night rather than day. I knew that Lucia’s inner self was full of such night-like anxiety and wavering.

Helping the demon Tricia sisters. And working as a night guard at gambling dens and salons in the pleasure district. It was a completely different image from ordinary students.

‘The night in the pleasure district was darkness itself.’

In the first place, that place didn’t start unless it was night.

And for Yunir, the goddess of darkness. Such unstable attributes that only night had were rather natural.

‘Yunir’s star.’

The vanished goddess of the night. Also, if Lucia’s uniqueness was related to that Yunir.

Finding the truth of the Pantheon and finding Yunir’s whereabouts. Lucia’s potential would definitely be a great help.

‘Unlocking potential. To put it simply. It would be turning the human Lucia into a demon.’

The decisive difference between humans and demons was the ability to use Yunir’s divine power. In other words, demonic energy.

Lucia, although she had created a vulva through sex with me. That vulva was just a kind of brand that was activated through me.

The demonic energy generated through the vulva meant that it was fundamentally the demonic energy that I created.

So, apart from that vulva, if she could realize demonic energy on her own. Lucia would be able to find the truth of the six temples that even I and Erti couldn’t find right away.

‘But how can a human use demonic energy?’

That was the problem.

I briefly recalled my own case. I was half human.

But now I could even use the essence of demonic energy, Breath. And that wasn’t even that unusual for me. Half of my blood contained the blood of my father, Lucifer, who was the Demon King.

I had awakened that sleeping demon blood through Cecilia’s bodily fluid contact. So maybe a similar method would work for Lucia.

‘Come to think of it, there were rumors that the Orhain family had demon blood mixed in.’

The south, Caceres, directly bordered the Demon King’s kingdom. The Orhain family, which ruled Caceres, was also a deep-rooted family on par with Reinhardt.

So, it wouldn’t be strange if there had been a secret intermarriage with demons in between. The men of the south were famous for sticking it anywhere there was a hole.

‘So, does that mean Lucia has a chance to awaken demonic energy?’

But that blood would be very thin compared to mine.

Lucia, who didn’t even have an awareness of being a demon bloodline, awakening as a demon like me. It wouldn’t be possible to do that all at once in the short time I had in this temple.

‘But Erti told me to leave it to her.’

She had told me that with a confident voice.

I decided to just lie down as I was and watch Erti’s actions.

A moment later. Erti moved.

---

Lucia couldn’t sleep.

That swordsmanship she had shared with Erti in this underground temple today wouldn’t leave her head.

The Lionheart Sword that drew a perfect line. She tirelessly reviewed the trajectory of that sword path and sword strike in her head. She wanted to find a way to properly deal with that sword.

But apart from not being able to sleep, her concentration was a little off.

‘Maybe it’s because of the fatigue from the sparring…’

Erti, who had faced Lucia, didn’t break a sweat. But Lucia desperately swung her sword at Erti.

But she couldn’t land a single proper hit, and in the end, she was the one who collapsed in the training ground.

It would have been strange if fatigue hadn’t accumulated while pushing herself like that.

Her muscles and every joint in her body seemed to be screaming.

‘And even Leister.’

Lucia and Yulian lay on either end of the bed. The people lying in between were Erti and Leister.

Leister lay right next to Lucia. And as soon as she fell asleep, she kept coming into Lucia’s arms.

‘This sleeping habit. It’s still the same.’

Leister was a childhood friend. But she was a friend whose news had become vague when she left the slums for Meiga.

The two were no different from childhood friends. When they collapsed together exhausted from sparring with their teacher. Leister would always fall asleep clinging to her like this.

So much had happened to the two of them in the meantime. But Lucia hadn’t even shared her feelings about reuniting with Leister.

‘Erti said that Leister hasn’t fully regained her ego yet.’

According to Erti, Leister, who had been completely consumed by demonic power, had lost her memories and ego as a result of the aftereffects.

Like this, she had become half an Ego Sword and was able to treat the aftereffects. But it would take time for her to return to her full mental state.

‘Still, I’ll have to spar tomorrow too… I have to force myself to sleep now…’

It was right then. She heard someone muttering to themselves next to her on the bed.

“Ugh… I can’t sleep because I’m stiff… Hooo…”

A woman’s voice. There was no way Leister could speak so well right now. It was Erti.

‘Erti-nim? Is Erti-nim also tired?’

She could feel her tossing and turning.

When she was sparring with her, she moved so lightly that she felt like a monster. But Erti might have accumulated her own fatigue.

‘She’s an Ego Sword, but from lying down to sleep… is that it?’

At that moment, Erti suddenly woke someone up.

“Hey. Yulian. Are you just going to fall asleep after using me as you please? Wake up!”

And a moment later, Yulian, who had woken up to those words, replied.

“Hmm. Erti? You weren’t asleep. What’s wrong?”

“Take responsibility! Thanks to you using me and Leister as sparring partners to your heart’s content. My whole body is screaming with muscle pain! I can’t sleep like this because my body is aching!”

Lucia pretended to be asleep and continued to listen to the two’s conversation.

“Well… it’s not wrong since I asked Erti to spar. No matter how much of an Erti you are, it wouldn’t have been easy to withstand Lucia’s speed sword.”

“That’s true. She’s clumsy with swordsmanship, but her instinctive combat sense is outstanding.”

Lucia felt a little hurt at those words.

‘Clumsy with swordsmanship. It’s true, but…’

Still, the words that followed were a compliment. Lucia, who had comforted herself inwardly. She was startled when she secretly watched the two.

‘Huh? What is Erti-nim suddenly trying to do?’

Erti raised her upper body from the bed. And she came out from under the blanket and shook Yulian’s body wildly.

“Hey! We have to spar tomorrow too! Are you going to leave me like this? I won’t be able to spar with Lucia-ssi if you do this!”

“Shh! The two who are sleeping will wake up, so please be a little quieter. Well, if that’s the case, there’s no helping it.”

Yulian, who said that, also came out from under the blanket.

“Then lie down on your stomach. I’ll loosen your muscles for you.”

Lucia hurriedly covered her mouth. She almost let out a voice.

‘Yulian-nim is giving a massage so easily?’

A highly renowned nobleman and Count in the Empire. There was no way it was common sense for such a Yulian to massage a woman himself.

But Erti very naturally lay down on the bed on her stomach. Yulian’s touch, caressing her body, wasn’t awkward either.

“Ugh… Ugh… Good. As expected of you, who knows my body well… Uheung… Th-there, I like it there… Hyaaang!”

And whether that massage skill was exquisite. Erti made a voice that seemed to melt every time Yulian’s hand touched her.

‘Erti-nim… This is strange… That’s… It sounds like a moan.’

Like the moaning of a woman who was sexually aroused. Erti’s voice was erotic.

Then for a moment, Yulian’s touch stopped.

“Ugh? No… More, do more! It felt good there… More… More…”

“Clothes are getting in the way. Erti. So I can’t massage you very actively.”

“I-is that so? Haa… Good. Then as much as you want.”

Erti, who had raised her body for a moment, threw off her clothes without hesitation.

It was night, but Erti had turned on orange lighting in this bedroom. So Erti’s naked body, tinged with orange light, was all visible to Lucia as well.

‘Erti-nim, what is this. Her body…’

She had felt it even when she was wearing clothes. But it was beyond her imagination when she took them off.

A pair of huge breasts that could be compared to Lilia Her Majesty. And childbearing hips and buttocks. Her skin was also as white as porcelain.

If Lucia was a man. She wouldn’t have been able to stand it after seeing that naked body.

‘I-is she even taking off her underwear?’

And Erti didn’t seem embarrassed at all to take off her clothes in front of Yulian.

In that moment, Lucia remembered the lewd talk that Erti had been spouting alone.

‘Could it be that she really shared sex with Yulian-nim?’

But Lucia soon denied that thought.

Erti was a Holy Sword, and the sword of Sword Empress Atlina von Reinhardt. There was no way such a Holy Sword would be in a relationship where she mixed bodies with the descendant of the Sword Empress. It was too disrespectful of a thought.

‘No. Erti-nim is Jedin’s Holy Sword. What kind of delusions am I having?’

And if Erti had really seduced Yulian with that lewd, no, beautiful body.

Yulian, who was now a famous Grand Duke even in the Empire. There was no way he would have stuck it in a sword.

‘That’s… an act of abandoning human dignity.’

Erti’s familiarity with the sword was probably to the extent that a swordsman was familiar with a sword.

It was then. Erti, who had been lying on her stomach receiving a massage with all her clothes off. This time, she turned her body over and lay on her back in a proper posture.

“Heuung… Good… If you loosen it there too… It’ll feel very refreshing… Kyaat!”

Lucia almost doubted her eyes.

Yulian’s hand went towards Erti’s lower body. Erti, who was stimulated in that secret place, let out a moan as it was.
